FIELD: process engineering. ^ SUBSTANCE: invention relates to sorption cleaning of air of nitrogen, sulfur oxides and hydrogen sulfide. Sorbent is produced by mixing 100 g of fine Portland cement 500, 100 g of Astrakhan Region boxes with 100 cm3 of 10%-water solution of table salt, and making granules with 0.5 - 5 cm-diameter. Produced mix is hardened and placed in running water unless negative reaction to chloride-ion. After drying, granules are placed in 40%-solution of diethanolamine for 1 h. Then, granules are placed onto sieve to be dried in air flow. Sorbet features the following chemical composition, in wt %: CaO - 40.0, SiO2 -15.0, NH(CH2)4OH2 - 5.0, H2O - 5.0. ^ EFFECT: efficient air cleaning. ^ 2 cl, 2 tbl |
